Cybersecurity in the quantum era: Assessing the impact of quantum computing on infrastructure

Quantum computing poses a major threat to current security systems because it can break traditional encryption methods that protect critical infrastructure and cloud services. This paper examines how quantum computing affects different layers of infrastructure (from applications to networks) and proposes moving toward quantum-resistant cryptography (encryption methods designed to withstand quantum computer attacks) as a protective strategy. The authors advocate for collaboration across sectors to develop and implement these new security approaches before quantum threats become critical.
